Definitions

  • the present invention relates to a filter construction and, more particularly to a soot filter adapted to be disposed in an exhaust gas stream of air-compressing internal combustion engines.
  • the aim underlying the present invention essentially resides in arranging and constructing a soot filter in such a manner that, an automatic burning-off of the soot filtered out of the exhaust gas stream occurs under physical operating conditions of the internal combustion engine relevant for a burning-off the soot.
  • the underlying problems are solved according to the present invention by providing a cylindrical filter housing arranged in proximity of the outlet or exhaust gas line of an internal combustion engine with inlet pipe connecting studs, which extends radially or tangentially from the internal combustion engine, being connected to the cylindrical filter housing.
  • Ceramic fiber material in hollow cylindrical shape is arranged in the cylindrical filter housing and spaced at a distance from the circumferential wall of the filter housing.
  • the ceramic fiber material consists of an outer layer of loose ceramic fiber wadding and of an inner woven ceramic fiber mat.
  • a hollow space inside of the ceramic fiber material is connected with the exhaust gas line in the axial direction.
  • apertured sheet metal members may be disposed in the filter housing for radially inwardly and outwardly supporting the ceramic fiber material in the housing.
  • a wire, mesh having a small mesh size may be arranged between the woven ceramic fiber mat and the inner apertured sheet metal member. Additionally, a further wire mesh, having large mesh size, may be provided between the small mesh size wire mesh and the inner apertured sheet metal member in order to improve flow conditions of the exhaust gases through the filter.
  • Another object of the present invention resides in providing a soot filter for exhaust gases of air-compressing internal combustion engines which is simple in construction, yet is highly effective for burning-off the filtered-out soot without requiring an external ignition source.
  • a further object of the present invention resides in providing a soot filter adapted to be located in an exhaust gas stream of air-compressing internal combustion engines which operates efficiently without requiring a supply of external energy.
  • a still further object of the present invention resides in providing a soot filter of the type described above which is so constructed and arranged as to avoid local overheating of the filter.
  • Another object of the present invention resides in providing a soot filter for exhaust gases of air-compressing internal combustion engines, which assures a sufficient supply of oxygen for burning-off filtered-out soot particles and which facilitates a removal of burned-off hydrocarbon particles.
  • FIG. 1 is an end elevational view of a soot filter in accordance with the present invention
  • FIG. 2 is a plan view on the soot filter of FIG. 1;
  • FIG. 3 is a partial cross-sectional view, on an enlarged scale, through the soot filter of FIGS. 1 and 2.
  • a soot filter consists of a cylindrical filter housing 1 having connected thereto tangentially terminating filter inlet pipe connecting studs 2 which, in turn, are adapted to be secured by means of flanges 3 directly at the outlet or exhaust side of an internal combustion engine (not shown).
  • Ceramic fiber material generally designated by reference numeral 6, of a hollow cylindrical form is arranged inside of the filter housing 1 between an outer apertured sheet metal member 4 and an inner apertured sheet metal member 5 in such a manner that exhaust gases entering through the inlet pipe connections 2 are circumferentially distributed in the filter housing 1 radially outside of the apertured sheet metal member 4 and then pass radially through the ceramic fiber material 6 and, exit from a cylindrical space 7, defined inside of the apertured sheet metal member 5, through a line 8 which connects the filter housing 1 to an exhaust pipe system (not shown) of the internal combustion engine.
  • the ceramic fiber material 6 between the apertured sheet metal members 4 and 5 consists of a radially outer layer of loose ceramic fiber wadding 9 and a radially inner layer of woven ceramic fiber matting 10 supporting the ceramic fiber wadding 9.
  • the ceramic fiber mat 10 is supported by a wire mesh 11 having a small mesh size with a wire mesh 12 having a mesh size larger than that of the wire mesh 11, being arranged between the wire mesh 11 and the inner apertured sheet metal member 5.
